MOSCOW (AP) _ A bus exploded in central Siberia in Russia, killing at least 11 coal miners, police investigating the incident said Friday.

There were no survivors from Thursday's blast, which may have been caused by a faulty fuel cylinder, police said, quoted by the Interfax news agency.

Police have not ruled out foul play and have offered a reward for information, the report said.

The bus, full of coal miners, exploded as it passed a gas station in Kiselyovsk, about 1,850 miles east of Moscow. The blast also destroyed a passenger car following the bus, the ITAR-Tass news agency said.

The car's driver was thrown onto a snowdrift that saved his life.
